Red face Tyre and wheel upsize for UNO 45.

Hi guys, i want to change my uno 1ltr petrol tyres and wheel to 14" yokohama es100 185/60/14 on palio alloys. 1: are they going to be too heavy for the car to handle. 2: are yoko advan neovas available in 175/60/14 in india?
I am now running the car on stock set 145/80/13.
I want a performance tyre because of future plans.
Thanks guys in advance.

With 185/60/14 you are going way overboard. I feel 165/60/13 should be the right upsize. I'd recommend Bridgestone Potenza GIII. Do you really need Advan Neova's that last 10,000 kms max? And don't think of upsizing to Palio alloys.

How about michelin in 175 or 185/60/13 because Bridgestone i feel has a softer compound.

Would you please explain your reasoning for the benefit of all concerned?

With your stock 145/80R13,
from the perspective of rolling diameter, you have 13" of metal, sitting on 4.567 inches of rubber, giving a rolling diameter of
22.134 inches.

Now to keep similar rolling diameter, if you must use a 14 inch wheel, you have to reduce the rubber by 0.5 inch all around.

So your 14" wheel should sit on 4.067 inches of rubber.

This can be achieved by
172 mm wide tires of 60% aspect ratio [172/60R14] or
159 mm wide tires of 65% aspect ratio [159/65R14] or
148 mm wide tires of 70% aspect ratio [148/70R14].

Depending on clearances available or not, fat rubber could rub on the inner edges while steering hard-a-port or hard-a-starboard. This will need to be experimentally investigated.

It is typical of hot-rodders to use wide wheels with negative offset and get a tinsmith to flare the fenders. One may also need to beef up the bearings and pay attention to steering geometry.

WW - Do keep in mind that if you do not have Power steering then with 185's your steering effort is going to increase substantially & she might become a pain to drive in the city.

Also if fitting 14" do a trial fitment first & make sure that there is not wheels arch fouling issues.

IN 13"
165/70 R13 and 185/60 R13 are the best possible upsizes.
165/70 R13 very difficult to get.
185/60 R13 available with BS, Michelin and YOKO.

In 14"
175/60 R14 is best available inch-up size.
I think avaialble only with YOKO or may be GY.

@iraghava please check if this is OK.

Your UNO doesn't have a Power steering and with a 185 width tyre you are asking for a rock hard wheel. The stock size I think is 155/xx/13. 185 will increase your contact patch. Not only that, the Uno wheel wells are not too comfortable with 14" wheels and nothing wider than 165. Try going overboard and you will learn it the hard way. You will have the tyres scraping the wheel archs and the suspension will go for a toss sooner than you think. Whoever on Fiatforum tried it might be experiencing this.

Hey moral i tried the wheels but the tyres were the stock palio size, and they were in bad condition so the ride was bad but steering was no problem and it did not touch the arches.

(In 14"
175/60 R14 is best available inch-up size.
I think avaialble only with YOKO or may be GY.)

Where can i get this size.Advan neova's are available in this size. Moral thats the reason i asked for them.

I stand corrected about the wheel well brush ups. It fits. I confirmed it from a user. Sorry.

This will give you an idea of how it'll look:

This guy isn't in India and I got this picture of the net. Some info I read while saving these pictures confirmed that 14 x 5.5 rims can be fitted.
